On Area 51: Escape, at the very end, instead of finding a way out, you can go with Elvis. Once Elvis says, "Oh, no! We have a problem! It's a single seater!", run up to the consoles. Stand next to the console farthest away from the hangar doors. From that spot, stand as close to Jonathan and Elvis as you can. You should be able to hear them talking. After they're done, wait until the music changes. Once this happens, press the B Button on both of the consoles. The level should end. (Good way to get Invincibility, [Agent, 3:50 or less]).
